`.applicatioil led November 9,1925.` Serial No. 67,893.

This invention relates to the insertion of fasteners and is illustratedherein as em# bodie-d in a machine particularly adapted to insert blindor invisible eyelets.

5 In the manufacture of boots and shoes blind and invisible eyelets arecommonly inserted by a machine provided with. a setting tool having asmall clenching shoulder arranged to be introduced from one side of thework through a lacing hole so as to meet and clench the entering endofthe eyelet barrel.- between adjacent layers of the work. In operatingmachines of this character7 difliculties at times are met with inforcing the layer of the work beneath which the eyelets are tov beclenched past the clenching shoulder of the setting tool. If this layerof the work (the upper leather in the case of invisible eyeleting) doesnot pass the f clenching shoulder by the time the entering end of theeyelet barrel reaches the clenching shoulder, the prongs of the eyeletare likely either to pass upwardlyl into the lacing hole so that theyare visible in the iinished work or to enter the substance of the upperleather as they spread7 thus enlarge ing the lacing hole.,

It is accordingly an obyectof the present invention to overcome thisdifficulty by providing an improved fastener-inserting machineorganization arranged to ensure that the layer of the work beneath whichthe fasteners are to be clenched is forcedk past the clenching surfaceof the setting tool before the insertion of each fastener. Thus theillustrated machine is kprovided with novel means arranged tol engagethe work substantially at the edge of the lacing hole upon the sideopposite that from which the setting tool is introduced and to force thelayerbeneath which the fasteners are to be clenched past the clenchingshoulder ofthe setting too-l. Preferably, and as illustrated herein,this means for forcing a layer of the work past the clenching shoulderof the setting tool comprisesa plurality of lingers surroundingthefastenerinserting tool or bottom set of the machine and arranged, afterthey have forced a layer of the work past the clenching shoulder of thesetting tool, to be moved radially away fromthe lacinghole so. as topermit the insertion and clenching ofi the fastener. l

l/Tith the above and other objects and features in view, the inventionwillvnow be ydescribed in connection with the accompanyving drawings andpointed out in the claims.

The invention is illust-rated herein as embodiedin an eyelet-insertingmachine of the type disclosed in United States Letters Patent No.1,205,277, granted Nov. 21, 1916, on an. application of Walter ShawJ towhich reference maybe had for a more detailed description of the machinethan is included herein.

The iiiusaaedmaehin is provided Wah a main' cam shaft '12 fromfwhich thevari#` ous parts of the machine are operated. These parts include alever14 arranged to carry an eyelets-setting tool 16 provided with aclenching shoulder 18. As illustrated this setting tool is a combinedpunch and set and is operative to punch the holes in which the eyeletsare to be inserted as well as to feed the work from punching toeyelet-inserting position. With these purposes in View, the machine isprovided with a punch block 20 and witha presser foot 22 moved out of`engagement with the work during the feeding movement of the setting tool161 and vclamping the work against the work table 24 of the machineduring the re turn movement of the setting tool after an eyelet has beenset. The machine is also provided with an eyelet-inserting vtool orbottom set 26 bored to receive a spindle 28 arranged for reciprocatingmovement to take eyelets one at a time from a raceway 30.

and hold them in ali'nement with the set-l tingy tool as they areintroduced intov the holes punched inthe work.

In ordervtovensure that they layer of the work beneath which the eyeletsare to be clenched.v (the upperleather in the case. of invisibleeyeleting) is past the clenchlng machine.

shoulder of the setting tool before the prongs of the eyelet are spreadduring the clenching operation, the illustrated machine is provided witha plurality of resilient fingers 32 surrounding the eyelet-insertingtool 26 and provided with flat end portions 34 substantially surroundingthe spindle'` 28, the fingers 32 being bent inwardly at the top andarranged to be brought into engagement with the work after it has beenfed to eyeletinserting position but before the insertion of the eyeletso as to engage the work over an area extending to the edge of thelacing hole on the side of the work opposite to that from which thesetting tool is introduced, endwise movement of lingers 32 then forcingthe upper layer of the work past the clenching shoulder 18 of thesetting tool. Fingers 32 are carried by a ring 38 mounted for slidingmovement on the eyelet-inserting tool 26 and supported by a spring 40bearing at its lower end upon a collar 42 secured to the inserting tool26. Endwise movement of fingers 32 relatively to the inserting tool 2.6is limited by a pin-andslot connection 43, the slot, however, being ofsufficient Width to permit a certain amount of rotary movement oflingers 32 and ring 38 upon the insertin g tool 26. The inserting tool26 is pro,- vided near its upper end with a cam 44 illustrated as havingthree elevated portions arranged to engage the inner surfaces of thethree fingers 32 and, when rotary movement is imparted to ngers 32, toforce them outwardly radially of the lacing hole so as to permit thepassage of an eyelet between fingers 32 as it is introduced into thelacing hole. For this purposevthe ring 38 is provided with a Iball 46located in a socket formed in a two-part block 48 arranged for slidingmovement. in a slot 50 formed in the upwardly extending arm yof a bellcrank lever 52 pivoted at 54 to the frame'of the llhe other arm of thebell crank lever 52 is provided with a cam roll 56 located in a suitablyformed cam groove 58 formed in a cam member 60 carried by shaft 12.

In the operation of the machine, after the work has been punched by thesetting tool and fed to eyelet-inserting position,the eyelet-insertingtool 26 with lits spindle 28 is moved upwardly to pick an eyelet fromthe end of the raceway 3() which is thenwithdrawn. At this time fingers32 are held by cam 44 away from spindle 28, as shown in Fig. 3, so that,the eyelet may drop down and rest upon a seat 62 formed at the upper endof the eyelet-inserting tool 26. Then as cam 60 rotates, bell cranklever 52 is rocked so as to bring fingers 32 opposite to the lowportions of cam 44, whereupon the upper ends 34 of these fingers springinwardly, as shown in Fig. 4. As the inserting tool 26 moves upwardly,fingers 32 engage the work at the edge of the lacing hole and force thework lengthwise of the setting tool until the layer beneath which theeyelets are to be clenched, illustrated at 64, is forced past theclenching shoulder 18 of the setting tool and into engagement with anabutment 65 carried thereby, as shown in Fig. 5. Bell crank lever 52 isthen rocked to bring fingers 32 opposite the raised portion of cam 44.Fingers 32 are thus moved outwardly, and as the inserting tool 26continues its upward movement, spring 40 is compressed, as shown in Fig.6. upwardly between the upper ends of fingers 32 and its barrel passeslthrough the lower layers (such as the facing 66 and eyelet stay 68) andis clenched by the clenching shoulder 18 between the layers of the work.Thereafter the eyelet-inserting tool 26 is lowered, the work being heldagainst movement by presser foot 22, and the setting tool 16 iswithdrawn and returned to punching position. y

In the illustrated machine the eyelet-setting tool 16 is formed with ashank tapered for reception by a diverging opening 70 formed in a toolholder 72 carried by lever 14. The tapered shank of the setting` toolmay extend clear to the clenching shoulder 18, as at 74 in Fig. 8, or acylindrical portion 7 6 may be interposed between the clenching shoulderand the tapered shank, as illustrated in Fig. 7, as may be desired.
